Development of a Spiral Flow ICP Torch as a New Low-gas-flow Torch for Axially Viewing ICP Optical Emission Spectrometry
A spiral flow ICP torch for axially viewing inductively coupled plasma optical emission spectrometry (axially viewing ICPOES) was developed as a new low-gas-flow torch. Since the spiral flow ICP torch could sustain a stable ICP at Ar plasma gas flow rate of 9 L min(-1) with 1.5 kW RF forward power and since the spiral flow ICP obtained showed analytical performance similar to a standard ICP, it is expected to be an alternative ICP torch for axially viewing ICPOES.
